PATENT OFFICE JOHN T. AUSTIN, 0F HARTFORD, CONNECTICUT, ASSIGNOR TO THE AUSTIN ORGAN COM- PANY, OF HARTFORD, CONNECTICUT, A CORPORATION OF CONNECTICUT y COMBINATION ORGAN STOP ACTION Application led May 20,

This invention relates to organs of the type having traces by means of which various combinations of stops can be operated.

A pipe organ usually comprises a number of manual organs or sub-organs, such as the great, choir, and swell, and a pedal organ or sub-organ, and each sub-organ is provided with suitable stop actions by means of which the several registers of` pipes can be opened or closed at will.

It is usual to provide organs with means by. which the various combinations of stops can be readily and quickly made up and operated, and such means includes what is known in the art as traces Traces of this kind are shown in my earlier Patent No. 1,07 8,079, dated November 11, 1913. In some instances, the stop actions of the pedal g; organ are entirely independent of the com bination stop actions of the manual so that, when a manual combination stop action is operated, the stop actions of the pedal organ are not affected or disturbed. Some organists prefer this arrangement. It has been proposed to provide organs wherein the pedal stop actions and the manual stop actions are associated in such manner as to be made up in. various combinations, but

-- in this arrangement, when a trace is operated through one of the manipulative devices associated with the manual, the stop actions of the pedal or an are disturbed. This arrangement is pre erred by some ory y ganists, but others wish the pedal stop ac tions to be operated entirely independently of the manual stop actions, as in the first instance.L

The aim of the present invention is to provide an improved arrangement by means of which the pedal stop actions may, at

will, either be associated with the combination stop actions of the manual or may be entirely divorced from the manual stop actions, thus allowing for flexibility and selectiveness and meeting the requirements of all organists. f

A further aim of the invention is to provide an improved organ mechanism havingy a trace mechanism provided with actuators 5U associated with the manual stop actions,

and actuators associated with the pedal stop actions, the latter actuators being rendered effective and ineffective at will, and the mechanism being characterized by its extreme simplicity in construction, itscompactness in arrangement, and the ease and facility with which it may be set up andl operated. i

Other objects will be in part obvious, and l in part pointed out more in detail hereinafter. n

rlhe invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exempliiied in the construction herein 65 after set forth and the scope of the application of which will be indicated in the appended claims.

In the accompanying drawing, wherein I have shown, for illustrative purposes, one of 'l0` the embodiments which the present invention may take,

Referring to the drawing in detail, 10 designates the skeleton rollers of one set of stop action operating devices which, for cony n venience in description, may be assumed are associated with the swell organ, or any one of the manual sub-organs. 1l designates the skeleton rollers of another set of stop action operating devices -which, for convenience, A may be assumed as beingassociated with the pedal organ. The skeleton rollers 10 are adapted to be individually oscillated about their axes by suitable stop keys or pellets convenient to the hands of the organist, and these rollers may be operatively connected tothe several registers of pipes of which the manual is made up, the manipulative means and connections not being illustrated, as they may be of any suitable construction. In thisy connection, reference may be had to my said Patent No. 1,079,078. The rollers 11 are operatively connected to the several registers of pipes of which the pedal organ or sub-organ is made up, and these rollers may be individually oscillated about their axes by suitable foot or hand pistons, which are not shown, as such arrangements are old and well known in the art. Itis, of course, understood that the two sets of suitable actions represented by the rollers 10 and 11 may be associated with any of the sub-organs of which the general organ is made up.

Extending through the rollers 10 and 11 is a trace bar 12 on one end of which are mounted the usual actuators or cams 13 for the several rollers 10, there being a cam 13 for each roller 10. These cams or actuators, in the present illustrative disclosure, are shown as being similar in construction and operation to the actuators disclosed in my said Patent No. 1,079,078. Each comprises a T-shaped resilient member pivoted on a stud 14 projecting laterally from the trace bar 12 and having a rounded head 15. Each actuator has a pair of bosses 16 which provide concavities adapted to selectively receive the rounded head 15 of that stud which succeeds the one on which the particular actuator is pivoted. Thus, each of these actuators is settable into two separate positions, in one of which the upper arm extends above the upper end of the trace and the lower concavity receives the stud, and in the other of which the lower arm extends below the trace and the upper concavity receives the stud. rIhese actuators are placed under tension or sprung so that they are effective at all times in each of the set positions.

Also pivotally carried by the main trace bar 12 is a plurality of actuators or cams 17 which are respectively associated with the stop actions of the pedal organ; that is to say, with the rollers 11. These actuators or cams 17 are similar in construction to the cams 13 but are mounted in a somewhat different manner in order that they may be rendered eiective and ineffective at will. In the present instance, these actuators 17 are loosely pivoted on studs 14 and have bosses 19 similar to the bosses 16 of the actuators 13. As stated, these actuators are loosely pivoted; that is to say, they are not resiliently held in such manner that they retain their positions with respect to the studs in the absence of other means for holding them in those positions.

For the purpose of holding the actuators 17 in set positions there is provided a locking device which is here shown in the form of a secondary bar 25 provided with a plurality of spring elements adapted, when the bar is in operative position, to engage the actuators 17, and when in inoperative position to leave those actuators free. In the present instance, this secondary bar 25 is located along the side of and parallel to that portion of the main trace which is provided with the actuators 17, the actuators being located between that trace and the bar 25. The bar may be supported for slidable movement in any suitable manner as, for example, by means of rivets 26 projecting laterally from the main trace and having heads 27. The spring elements on the secondary or locking bar 25 may take various forms. Each is here shown as comprising a U-shaped spring member 28, the free or inner arm 29 of which is adapted to engage the bosses 19 when the locking bar is in the operative position shown by dotted lines in Figs. 2 and 3. The longer arms of the spring members extend downwardly along the outer face of the locking bar, and have T-heads 30 at their upper ends. These outer arms extend through pressed out bridge portions 31 on the locking bar, and the heads rest upon these bridge portions. The outer arms of the spring members are bowed, as at 32, so as to give added resiliency to these members.

The secondary or locking bar 25 has an operative position, shown by dotted lilies in F ig. 3, and an inoperative position, shown by full lines in that figure. 1n order to move this bar from one position to another, any suitable arrangement may be provided such, for example, as a roller 35 associated with a lever cam 36 which forms a connection between the main trace and the locking bar. The roller 35 may be similar to the other rollers, and is adapted to be operated by its own individual key or tablet. The lever cam 36 is pivoted to a stud 37, and has a pair of bosses 38 adapted to selectively receive the head of the first pin 18. The body portion of this cam is normally llexcd so that the cam of itself has suilicient resiliency to hold it in either of its set positions. The cam has arms 39 adapted to cooperate with the respective arms of the roller 35. It also has a connecting portion or finger 40 which terminates in a hook 41 adapted to engage a notch 42 in the upper edge of, and gcljacent the forward end of, the locking bar do.

The operation of my improved arrangement is briefly as follows: Assuming that the organist wishes to dissociate thepedal organ stop actions from the control of the traces in order that the various registers of pipes of the pedal organ will not be interfered with or disturbed by the trace when the latter is operated, the locking bar is brought to the inoperative position shown by full lines in Fig. 3 and in which position the spring elements 28 do not engage the actuators 17; therefore, these actuators are free to move or flop so that, when the trace is moved, these actuators do not disturb the positions of the rollers l1. Assuming now that an organist desires that the pedal stop actions be under the control of the trace, he can readily change the organ from one system to another by merely operating the manipulative device associated with the roller 35 so as to throw that roller to its other position, thereby depressing the cam 36 and causing the connecting portion 4() to move the locking bar to the left, that is to the dotted line position shown in Fig. 3. When this is done, the spring fingers 29 are engaged with the bosses 19 and thus resiliently hold the 'actuators 17 in their set; positions. The resistanceA of these actuators against movement is now greater than the resistance of the rollers 11 against movement so that, when the trace is moved as a whole, these rollers will be set in accordance with the set positions of thefactuators 17. l` he actuators 17 are settable when the locking bar 25 is in the position where spring fingers 29 engage with the bosses 19. If it is desired to throw the pedal stop actions out ofy the control of the trace, this can readily be done by moving the roller 35 back to the position shown in Fig. 2, thereby rendering the actuators 17 ineffective when the trace .is moved.

As many changes could be made in the above construction and many apparently widely different 'embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown inthe accompanying drawing shall be interpreted as illustrative and not' in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a mat-ter of language, might be said to fall therebetween.
